Description

Technical Field

[0001] The present invention relates to the technical field of gas pressure regulator testing, and in particular to an intelligent pressure regulator testing system and a use method thereof. Background Art

[0002] The static characteristic of a gas pressure regulator refers to the characteristic that the actual outlet pressure of the pressure regulator changes with the inlet pressure and flow rate. The national standard GB790-2020 stipulates the inspection process of the static characteristic test of urban gas pressure regulators in Article 7.6.1. First, when the inlet pressure is equal to P 1av , flow rate is (1.~1.2)Q min Under the working condition, adjust the outlet pressure of the pressure regulator to the initial outlet pressure P 2int , or use the initial state setting method explicitly stated by the manufacturer, complete the initial setting, and then perform subsequent operations to determine a static characteristic line.

[0003] In the prior art, document CN1753054A discloses a pressure regulator test system and test method, including a main gas circuit, on which an inlet pressure regulator, an inlet shutoff valve, a pressure regulator to be tested, and an outlet shutoff valve flow regulating valve are sequentially connected, and an inlet pressure gauge and an outlet pressure gauge are respectively provided at the inlet and outlet ends of the pressure regulator to be tested, respectively detecting the pressure values ​​at the inlet and outlet ends of the pressure regulator to be tested; a first branch is connected between the inlet pressure regulator and the inlet of the main gas circuit, a second branch is connected between the inlet shutoff valve and the inlet of the main gas circuit, a third branch is connected between the outlet shutoff valve, a seventh solenoid valve is provided on the third branch, the seventh solenoid valve is connected in series with the third controller, and is connected in parallel with the third solenoid valve, and the flow regulating valve adjusts the flow size at the outlet end of the main gas circuit. However, this solution cannot realize intelligent detection / testing.

[0004] Document CN103439125A discloses a gas pressure regulator pressure regulating performance detection device and detection method, which includes a gas circuit part and a control part. Its flow control valve, flow sensor and software PID control algorithm realize closed-loop control of flow, and provide accurate flow regulation for the outlet of the tested pressure regulator. The detection method steps are: start the test, initialize the device and variables, close the pressure measurement, outlet pressure measurement, pressure regulation static characteristic test, and determine whether the tested device is qualified; the test ends. Although this scheme has realized the intelligent testing of the gas pressure regulator to a certain extent, it still needs to be optimized.

[0005] At present, although domestic and foreign pressure regulator manufacturers have mature detection methods and detection equipment, they still face the following problems in the process of gas pressure regulator testing: for each specification (nominal diameter) of pressure regulator, an independent pipeline and detection platform must be set up, resulting in a large number of detection systems that usually occupy a very large area in the workshop. The average area of ​​each pipeline and detection platform is about 6 to 8 square meters. If 10 pipelines and detection platforms of different specifications are configured, more than 60 square meters of space is required; it is impossible to quickly switch the detection of pressure regulators of different specifications. Taking the switching of DN300 pressure regulator to DN100 pressure regulator as an example, the entire switching process (removal of DN300 pressure regulator and installation of DN100 pressure regulator) takes about one hour, and requires at least two people to cooperate with driving to complete. Summary of the invention

[0006] At least in order to solve the technical problems mentioned in the background technology, the present invention aims to provide an intelligent voltage regulator testing system and a method for using the same.

[0007] The present invention adopts the following technical solution.

[0008] An intelligent pressure regulator testing system comprises a gas supply main and an exhaust main, wherein an automatic control testing unit is connected between the gas supply main and the exhaust main, wherein the automatic control testing unit comprises a flow meter, a pressure transmitter, a temperature transmitter, a gas source pressure regulator (a pressure regulator for debugging the gas source pressure), a pressure regulator to be tested, a flow regulating valve, and an electric ball valve, wherein the flow meter is connected to the gas supply main, the electric ball valve is connected to the exhaust main, the flow meter, the pressure transmitter, the temperature transmitter, the gas source pressure regulator, the flow regulating valve, and the electric ball valve are all connected to a central control system, wherein a processing module of the central control system realizes the following functions when executing a program: controlling the flow meter, the pressure transmitter, the temperature transmitter, the gas source pressure regulator, the flow regulating valve, and the electric ball valve to open and close at a preset time and to operate according to corresponding set values; providing real-time feedback and recording of data fed back by the flow meter, the pressure transmitter, the temperature transmitter, the gas source pressure regulator, the flow regulating valve, and the electric ball valve, forming a flow-pressure relative curve with the obtained data, and outputting the curve synchronously with a preset threshold value to form a test result data graph.

[0009] Furthermore, the automatic control test unit also includes a first turntable and a second turntable that are spaced and coaxially arranged. Each turntable is provided with a plurality of short tube assemblies of different diameters. All the short tube assemblies are evenly arranged around the center of the turntable. The axis of the short tube assembly is parallel to the axis of the turntable. The short tube assembly of the first turntable is provided with a connection flow meter, a pressure transmitter, a temperature transmitter and an air source pressure regulator, and the short tube assembly of the second turntable is provided with a flow regulating valve and an electric ball valve; the air source pressure regulator, flow meter, flow regulating valve and electric ball valve are all fixedly connected to the corresponding short tube assemblies and can rotate synchronously with the operation of the turntable.

[0010] Furthermore, the central axes of the first turntable and the second turntable are both connected to motors, and the motors are connected to a central control system. The central control system controls the motors to rotate according to preset values ​​and pauses after the turntables rotate a specified angle.

[0011] Furthermore, the flow meter is connected to the air supply main pipe through a hose with a flange, and the electric ball valve is connected to the exhaust main pipe through a hose with a flange.

[0012] Furthermore, a number of short pipe assemblies of DN to DN400 mm can be arranged on each turntable.

[0013] In order to improve the stability of the test system, the width of each turntable is 1 / 3 to 3 / 4 of the length of the short tube assembly, and each short tube assembly is clamped and fixed by a tube clamp.

[0014] In order to further improve the stability of the test system, a limit hole is set on each turntable, and a clamping hole is set on the support below the limit hole. The limit rod is inserted into the limit hole and the clamping hole at the same time to limit the turntable. With such a structure, the test system can be double-stable. On the one hand, the turntable is fixed by stopping / pausing the motor, and on the other hand, the turntable is limited by the limit rod.

[0015] Furthermore, a pressure transmitter and a temperature transmitter are also provided on the short tube assembly of the second turntable.

[0016] A method for using the aforementioned intelligent voltage regulator testing system comprises the following steps:

[0017] Step 1, select a suitable short pipe assembly A according to the diameter of the voltage regulator to be tested;

[0018] Step 2, controlling the motor to rotate according to a preset value and causing the two turntables to rotate by a specified angle and then pause, at which time, the short tube assemblies A on the first turntable and the second turntable are facing and located on the same axis;

At this time, the gas supply pipe, flow meter, pressure transmitter, pressure regulator to be tested, temperature transmitter, flow control valve, electric ball valve, and exhaust pipe are connected together;

[0022] Step 6: According to the test requirements, the test parameters are set in the central control system, including pressure level, pressure setting value, upper limit value, lower limit value, flow value, valve opening, etc. The specific values ​​of the test parameters are set by technicians in this field according to standard specifications or user requirements;

[0023] Step 7, execute the test: real-time feedback, record the data fed back by the flow meter, pressure transmitter, temperature transmitter, flow control valve, and electric ball valve, form the obtained data into a flow-pressure relative curve, and output it synchronously with the preset threshold curve to form a test result data graph.

[0024] For easier operation, in step 2, after the turntable rotates a specified angle, the short tube assembly A is located to the side of the center of the turntable.

[0025] Beneficial effects: The present invention significantly reduces the space occupied by multiple pipelines and detection platforms in the workshop. Even if ten pipelines and detection platforms of different specifications are configured, only 10 square meters of space is needed to meet the requirements, which can reduce the space occupied by about 70% compared with the existing layout. The scheme of the present invention can realize the rapid switching of the detection of voltage regulators of different specifications. Taking the removal of DN300 voltage regulator and the installation of DN100 voltage regulator as an example, the time consumption of the whole switching process can be reduced to 20 to 30 minutes, and only one operator is needed to cooperate with the driving to complete it. The voltage regulator testing system of the present invention not only has good stability, but also has good flexibility during use, and has the advantage of convenient operation.

The first turntable 21 and the second turntable 22 have an operating space (total width) of two meters in the radial direction. Each turntable is provided with a plurality of short tube assemblies 25 of different diameters. All short tube assemblies 25 are evenly arranged around the center of the turntable. The axis of the short tube assembly 25 is parallel to the axis of the turntable.

[0043] Step 5, select a flanged hose of appropriate specifications to connect the gas supply pipe and the flow meter 10, and select a flanged hose of appropriate specifications to connect the exhaust pipe and the electric ball valve 14. At this time, the gas supply pipe, the flow meter 10, the pressure transmitter 11, the pressure regulator to be tested 18, the temperature transmitter 12, the flow control valve 13, the electric ball valve 14, and the exhaust pipe are connected together;

[0045] Step 7, execute the test: real-time feedback, record the data fed back by the flow meter 10, pressure transmitter 11, temperature transmitter 12, flow control valve 13, and electric ball valve 14, form the obtained data into a flow-pressure relative curve, and output it synchronously with the preset threshold curve to form a test result data graph.

[0046] In the initial state, if the short pipe assembly with a nominal diameter of DN40 is located at the high point of the turntable, and now the gas pressure regulator with a nominal diameter of DN100 needs to be tested, the operation process is as follows.

[0047] First, select a suitable short tube assembly A251 (select a short tube assembly A251 of DN100) according to the diameter (DN100) of the voltage regulator 18 to be tested; then, control the motor 23 to rotate according to the preset value and make the two rotating disks rotate by a specified angle and then pause. At this time, the short tube assemblies A251 on the first rotating disk 21 and the second rotating disk 22 are opposite and located on the same axis (the state at this time is as shown in FIG. 1 ). Figures 3 to 5 ); wherein, after the disk rotates by a specified angle, the short tube assembly A251 is located on the side of the center of the turntable, that is, the short tube assembly A251 is rotated to the side of the center of the turntable; then, the voltage regulator 18 to be tested is hoisted between the two short tube assemblies A251, and installed so that the two short tube assemblies A251 are connected to the voltage regulator 18 to be tested; then, the limit rod is inserted into one of the limit holes 26 and the card hole of the turntable at the same time to lock and limit the two turntables; then, a flanged hose of a suitable specification (i.e., a DN100 hose) is selected to connect the air supply main pipe and the flowmeter 10, and a flanged hose of a suitable specification (i.e., a DN100 hose) is selected ) connect the exhaust pipe with the electric ball valve 14. At this time, the gas supply pipe, flow meter 10, pressure transmitter 11, pressure regulator 18 to be tested, temperature transmitter 12, flow control valve 13, electric ball valve 14 and exhaust pipe are connected together; according to the test requirements, the test parameters are set in the central control system, including pressure level, pressure setting value, upper limit value, lower limit value, flow value, valve opening; execute the test: real-time feedback and record the data fed back by the flow meter 10, pressure transmitter 11, temperature transmitter 12, flow control valve 13 and electric ball valve 14, form the obtained data into a flow-pressure relative curve, and output it synchronously with the preset threshold curve to form a test result data graph, such as Figure 6 The figure shows the test result data of a gas pressure regulator.

[0048] After the test of the DN100 gas pressure regulator is completed, if the DN300 gas pressure regulator needs to be tested next, the operation process is as follows: first dismantle and remove the DN100 gas pressure regulator, and then, according to the diameter (DN300) of the pressure regulator 18 to be tested next, select a suitable short tube assembly B252 (select the DN300 short tube assembly B252); then take out the limit rod, and then control the motor 23 to rotate according to the preset value and make the two turntables rotate the specified angles respectively and then pause. At this time, the short tube assemblies B252 on the first turntable 21 and the second turntable 22 are opposite and located on the same axis; wherein, after the disk rotates the specified angle, the short tube assembly B252 is located on the center side of the turntable, that is, the short tube assembly B252 is rotated to the center side of the turntable; then, the pressure regulator 18 to be tested is hoisted between the two short tube assemblies B252, and installed so that the two short tube assemblies B252 are connected to the pressure regulator 18 to be tested; then, re-set the limit The rod is inserted into one of the limit holes 26 and the card hole of the turntable at the same time to lock and limit the two turntables; then, a flanged hose of appropriate specifications (i.e., a DN300 hose) is selected to connect the gas supply pipe and the flow meter 10, and a flanged hose of appropriate specifications (i.e., a DN300 hose) is selected to connect the exhaust pipe and the electric ball valve 14. At this time, the gas supply pipe, the flow meter 10, the pressure transmitter 11, the pressure regulator to be tested 18, the temperature transmitter 12, the flow control valve 13, the electric ball valve 14, and the exhaust pipe are connected together; according to the test requirements, the test parameters are set in the central control system, including pressure level, pressure setting value, upper limit value, lower limit value, flow value, and valve opening; execute the test: real-time feedback and record the data fed back by the flow meter 10, the pressure transmitter 11, the temperature transmitter 12, the flow control valve 13, and the electric ball valve 14, and the obtained data is formed into a flow-pressure relative curve, and synchronously output with the preset threshold curve to form a test result data graph. During the operation process described in this paragraph, when switching the gas pressure regulator, you only need to remove the original pressure regulator first, release the limit on the turntable, then turn the turntable to the appropriate position and install the new pressure regulator. The new pressure regulator is cleverly matched by turning the turntable to the appropriate angle, which realizes the flexible switching of the pressure regulator. The operation is very convenient and easy. Only one operator is required for the entire switching process, which takes 20 to 30 minutes to complete.

[0049] This solution significantly reduces the space occupied by multiple pipelines and detection platforms in the workshop. Eight pipelines and detection platforms of different specifications are configured, and the space used is about 10 square meters to meet the requirements. Compared with the existing layout, the space occupied can be reduced by about 70%; the adoption of this solution can achieve rapid switching of detection of voltage regulators of different specifications. Taking the removal of DN300 voltage regulator and the installation of DN100 voltage regulator as an example, the time consumption of the entire switching process can be reduced to 20 to 30 minutes, and only one operator is required to cooperate with the driving to complete it; the voltage regulator test system in the embodiment not only has good stability, but also has good flexibility during use, and also has the advantage of convenient operation, and is particularly flexible and easy during switching operations; when in use, the difficulty of operation before the voltage regulator test is reduced, and the test efficiency of the voltage regulator and the accuracy of the test results are greatly improved. The entire test process can be fed back, and the test results can be accurately fed back in the form of a curve (not the traditional point value results).
